HI
I am working on MAODV.could anybody please help me out from the follwing
problem releted to MAODV.
I have ported MAODV in ns-2.26.
whenever I run the simulation script ns.tcl I am getting following error:
[EMAIL PROTECTED] ex]$ ns ns.tcl 10 30 1
num_nodes is set 50
INITIALIZE THE LIST xListHead
Loading connection pattern ...
Loading scenarios file...
